 title: How do I setup a path alias?
 ---
 
-First, you need to add it to the Vite configuration. In `svelte.config.js` add [`vite.resolve.alias`](https://vitejs.dev/config/#resolve-alias):
+Aliases can be set in `svelte.config.js` as described in the [`configuration`](/docs/configuration#alias) docs.
 
-```js
-/// file: svelte.config.js
-// @filename: ambient.d.ts
-declare module 'path';
-
-// @filename: index.js
-import path from 'path';
-
-/** @type {import('@sveltejs/kit').Config} */
-const config = {
-	kit: {
-		vite: {
-			resolve: {
-				alias: {
-					$utils: path.resolve('./src/utils')
-				}
-			}
-		}
-	}
-};
-
-export default config;
-```
-
-Then, to make TypeScript aware of the alias, add it to `tsconfig.json` (for TypeScript users) or `jsconfig.json`:
-
-```json
-{
-	"compilerOptions": {
-		"paths": {
-			"$utils/*": ["src/utils/*"]
-		}
-	}
-}
-```
+Then run `npm run sync` or `npm run dev` (which will execute `sync`). SvelteKit will automatically generate the required alias configuration in `jsconfig.json` or `tsconfig.json`.
